Shake Weight for Men
Watch the videos for each gender. Notice a difference? Notice how one begins by alerting a group to something wrong with their bodies while the other one begins with an empowering, badass message? One ad highlights the necessity of looking sexy by using the product while the other ad highlights being powerful.
Oh and if getting pissed off at this stupid shit doesn't interest you just open the second link and listen to the video with your eyes closed. It sounds like something out of Queer As Folk. In a good way.
